On Tarsonis, Sarah Kerrigan was betrayed by her allies and left to die by the people she trusted most - but she survived, twisted by the terrifying zerg Overmind. As the Queen of Blades, she controlled the voracious zerg Swarm in a campaign of vengeance and retribution with a deathtoll numbering in the billions. Now, with her powers stripped and her mind finally free from the zerg influence, how much is really left of the woman who once was Sarah Kerrigan? Can her human side be redeemed... or does Kerrigan's fate forever lie within the Heart of the Swarm?

Sarah Kerrigan is on the loose. Even without the terrible powers of the Queen of Blades or the might of the Swarm at her command, the former Ghost remains a foe not to be taken lightly. But if the artifact really did set her free, then why is Kerrigan seeking out Zerg broods scattered throughout the Koprulu sector? Is she still pursuing her quest for vengeance, or has her transformation given Kerrigan a new purpose?
